' Application filed December 30, 1925i, Serial No. 78,405.

My invention relates to improvements in window ventilators to be used any place where aventilator of this character is suitable.

The object ofmy invention is to provide a window ventilator adapted to be placed below the lower sash when raised to allow of the passage of air between the upper end of the lower sash and the lower end of the upper sash and by means of which when in operative position a supply of fresh air can enter the place and at the same time being so arranged as to eliminate draft of the supply of air.

Another object of my invention is to provide a ventilator of this character which can be readily applied and removed from the 1 window and when placed in operative position beneath the lower sash completely closes the space made by raising the lower sash for the purpose above mentioned.

A further object of my invention is to provide a ventilator of this character which will not obstruct the light from entering the place and at the same time provide a simple, cheap and effective ventilator having certain details of structure and combination of parts hereinafter more fully set forth.

In the accompanying drawings Figure 1 is a perspective view of a window frame showing my improved ventilator applied below the lower sash.

Figure 2 is a transverse horizontal secner ends as indicated at 6, and as shown these; hinges are on the outside of the sections 4 and 5, so that any pressure from within the place will tend to lock the sections more tightly in the position shown in Figure 2 of the drawings when placed below the lower end of the sash when said sash is in a raised position; and when placed beneath the lower sash in such raised position of-windows of the usual construction by placing the outer ends ofthe sections-4 and 5 in the grooves or guide-ways 7 and 8 in the frame which is clearly shown in Figure 2,o f the draw.-

, ear

rarest caricaings and against the outer face of the hori zontal board which forms part of the lower. part of the window frame, it becomes a self lockihg device and is held firmly in this po-, sition even without the aid of thelowcr sash resting upon it.

The tops of the sections 4- and 5 are, rounded as indicated at 9 and the'bottoms of 5 said sections are rounded as indicated at'lO so as to meet the angle at which thebottom of the lower sash and the lower part "of the window frame are made, and thus when the placed in the position above referred to, the

lower sash is resting upon this device when space left by raising the lower sash for the.

purpose abovereferred to, is completely .closed,.air entering as above stated between the lower end of the upper sash and the upper end of the lower sash.

The section 5 is dprovided with a handle 11 as shown in the awings for convenience whereby the sections may be raised upwardly and drawn inwardly to break the hinge connection 6 for the purpose of removing the ventilator from the window frame below the sash as shown in dotted lines in Figure 2 of the drawings. This handle also serves the same purpose for handling the ventilator in inserting 1t in the grooves or guide-ways I 7 and 8 and placing it in the position shown in Figures land 2 'of the drawings. The frame or section 4 is provided'with an eyebolt 12 to which is connected a chain'l3 by means of snap hook 1 1. The opposite end of the chain 13 is provided with a snap hook 15 which snaps into a screw e e16 secured to the lower part of the win ow frarrel'? on the inside below the sill 18. This chain with snap hooks on both ends,'is so arran ed to guard against the possibility of its being accidentally dropped on the outside of the window when being inserted or removed, the snap hooks being used so that it can easily be disconnected if for any purpose it is desired to take said ventilator away from be made either solidor with glass panels 19' and 20 or, other translucent material used in the panels which will admit light and thus when the device is applied practically the same amount of light will pass through the window into the place While I have shown and described this specific construction, itwill be understood the window. The two sections 4 and 5 can that'slight variations mid a made therein a I claim is:-

without-de' arting'from my invention.

Ha g t us 'bed my invention, what" A ventilator at application to a' window frame having side grooves for asash and-a transversely slanting longitudinally shoull- -dered sill, said ventilator comprising two sections hin ed together on their ,outer faces and ada te to be positioned beneath said sash wit the ends of said sections seated in said grooves; a flexible-connection at-.

v tached to the inner rm of-one of said sec tions adjacent end and adapted for attachment to a support,-said 'connec-' tion constituting a means'f -ior said ventilator at the'hing'e point whereby the section ends, may be removed 3 from: said grooves, said connection further-preventing said ventilator from falling out. of 'th'e "dowwh'en inserting or .removing the. $'l e;f said'aventilator section's being rounded-top and against falling the adf'aoentrsash rail bottom and t e sill regard ess of the transverse angle the same may have whereby to ti htly seal the space between the said sash rai and window 8111 and permit the admission of air into the room between the toprail ofsaid sash and the bottom railof its companion sashand the of said sections'being arraii d to permit movement of-the connect endsyof the section's into theroom sections outwardly of the po'sdframe groovesaw said sections to hold the ventilator in place outwardly from said window en put in place. In testimony whereof, Ihave signed this specification. I p
